Hello, can you please provide more details? What query did you try to run, and what results did you expect?

[xiaowangAndyismengxin]

result = es.search(index='news')
print(result)
{'took': 0, 'timed_out': False, '_shards': {'total': 1, 'successful': 1, 'skipped': 0, 'failed': 0}, 'hits': {'total': {'value': 0, 'relation': 'eq'}, 'max_score': None, 'hits': []}}
even kibana says the data is exist

my code

from elasticsearch import Elasticsearch
import json

es = Elasticsearch(
    "https://elastic:E3VUUEUJ5GcLxc2Pp%3D7s@localhost:9200/",
    verify_certs=False,
    ssl_show_warn=False,
)

es.options(ignore_status=404).indices.delete(index="news")
es.options(ignore_status=400).indices.create(index="news")

for data in enumerate(json.load(open("novel_data.json", encoding="UTF-8"))):
    es.create(index="news", id=str(data[0]), body=data[1])
    print(f"数据插入成功 id: {data[0]}")

data = {
    "title": "985保送路线有哪些？",
}
status = es.update(index="news", id="3", body={"doc": data})
print(status)
doc = es.get(index="news", id="3")
print(doc)

status = es.delete(index="news", id="3")
print(status)
result = es.search(index="news")
print(result)

output:

Elasticsearch is a near real time system, where documents are not indexed directly after having been created: https://www.elastic.co/guide/en/elasticsearch/reference/current/near-real-time.html.

Get, update and delete are not affected, but search is. To fix this, you need to either wait or refresh your index before searching:

es.indices.refresh(index="news")

result = es.search(index="news")
print(result)

Oh, thank you.
